[0035] A flexible shaft mounting structure for glass bending and tempering, comprising a plurality of conveying wheels 2, a plurality of cold air conveying pipes 3, and a plurality of support bases 4; the cold air conveying pipes 3 extend along the Y direction, and the plurality of cold air conveying pipes 3 are arranged in parallel;

[0036] The support seat 4 includes a connecting seat 42, a joint bearing 43 and two lateral hinge seats 41;

[0037] A rotating cavity 421 is provided in the middle of the connecting seat 42; both ends of the connecting seat 42 extend in directions perpendicular to the axis of the rotating cavity 421; a rotating cavity 410 is provided at the top of the lateral hinge seat 41; both ends of the connecting seat 42 are rotatably inserted into the two rotating cavities 410; the joint bearing 43 is rotatably mounted in the rotating cavity 421; the bottom of the lateral hinge seat 41 is fixed to the corresponding Z-direction end face of the cold air delivery pipe 3;

[0038] Multiple flexible shafts 1 extend along the X direction respectively, and each flexible shaft 1 passes through multiple joint bearings 43 located above different cold air delivery pipes 3 in sequence; the outer peripheral surface of the flexible shaft 1 is covered with multiple delivery wheels 2; at least one delivery wheel 2 is distributed between two adjacent rotating chambers 421.

[0039] Figure 1-3 The figure shows a structural schematic diagram of a flexible shaft installation structure for glass bending and tempering according to the present invention. Figure 4 and Figure 5 It is a structural diagram of the support base 4.

[0040] Figure 1 Multiple cold air delivery pipes 3 extend in the Y direction respectively, and the Z-direction end face of each cold air delivery pipe 3 is installed with multiple support seats 4 arranged at intervals along the Y-axis direction. The flexible shaft 1 extends in the X direction, and each flexible shaft 1 is connected to the multiple support seats 4 arranged in a row along the X direction through multiple joint bearings 43; so that the flexible shaft 1 is mounted above the Z-direction end faces of the multiple cold air delivery pipes 3, and the multiple flexible shafts 1 are parallel and spaced along the Y direction. The outer circumference of each flexible shaft 1 is equipped with multiple conveying wheels 2. The flexible shaft 1 can rotate in the multiple support seats 4 through the joint bearings 43, so that the flexible shaft 1 will not get stuck and fail to rotate.

[0041] At least one conveying wheel 2 is arranged between two adjacent support seats 4 along the X direction. The Z-direction wheel surfaces of the multiple conveying wheels 2 located on the multiple flexible shafts 1 form a curved arc surface for supporting and conveying the tempered glass, so that the multiple flexible shafts 1 can drive the multiple conveying wheels 2 to rotate synchronously and convey the tempered glass along the Y direction.

[0042] Furthermore, it also includes two support tubes 6, a plurality of transmission wheels 5, a plurality of transmission bearings 8, a plurality of connecting shafts 12 and a plurality of cross universal couplings 11;

[0043] The support tube 6 extends along the Y direction, and the two support tubes 6 are respectively arranged from the outside close to the two cold air delivery tubes 3 located at the edge;

[0044] The plurality of transmission bearings 8 are divided into two groups, and the plurality of transmission bearings 8 in the same group are arranged at intervals along the Y direction on the Z direction end surface of one of the support tubes 6;

[0045] One end of the connecting shaft 12 is fitted with the transmission wheel 5 , and the other end of the connecting shaft 12 passes through the transmission bearing 8 and is connected to one end of the cross universal joint 11 , and the other ends of the two cross universal joints 11 are respectively connected to the two ends of the flexible shaft 1 .

[0046] like Figure 1 and Figure 2 As shown, when the curvature of the glass to be prepared is greater than the bendability of the soft shaft 1, the arc bending mechanism drives multiple cold air delivery tubes 3 to bend and continuously increase the curvature to achieve the curvature required by the process; since the bendability of the soft shaft 1 is limited, if the cross universal joint 11 is not used, the two ends of the soft shaft 1 are rigidly connected to the other ends of the two connecting shafts 12, or the two ends of the soft shaft 1 are respectively inserted into the installation structure of the two transmission wheels 5, the flexible shaft 1 will not be able to bend enough, and the flexible shaft 1 will hold back the bending of multiple cold air delivery tubes 3, resulting in a stuck state when the arc bending mechanism drives the multiple cold air delivery tubes 3 to continuously increase the curvature, thereby hindering the operation of the arc bending mechanism to drive the multiple cold air delivery tubes 3 to bend.

[0047] Therefore, the two ends of the flexible shaft 1 are respectively connected to the other ends of the two connecting shafts 12 inserted into the two transmission wheels 5 through two cross universal joints 11, so that the bending mechanism can drive the bending operation of multiple cold air delivery pipes 3 without being restricted by the bendability of the flexible shaft 1, thereby avoiding the occurrence of the above phenomenon.

[0048] Furthermore, the outer side surface of the support tube 6 away from the cold air delivery tube 3 is used to install a sprocket transmission mechanism 10 that drives the multiple transmission wheels 5.

[0049] like Figure 1As shown, the driving device can drive multiple transmission wheels 5 to rotate synchronously through the sprocket transmission mechanism 10, and drive multiple flexible shafts 1 to rotate synchronously through multiple connecting shafts 12.

[0050] In a preferred embodiment, a connecting plate 7 is further included;

[0051] The connecting plate 7 is used to connect one end of the supporting tube 6 and one end of the adjacent cold air delivery tube 3 .

[0052] like Figure 1 and Figure 2 As shown, one end of the support tube 6 and one end of the adjacent cold air delivery tube 3 are connected together by a connecting plate 7, so that the support tube 6 can bend and move along with the adjacent cold air delivery tube 3.

[0053] Preferably, the outer peripheral surface of the conveying wheel 2 is wrapped with aramid heat insulation cotton.

[0054] The material of the conveying wheel 2 is metal, and the outer surface of the conveying wheel 2 is wrapped with aramid heat-insulating cotton to prevent the tempered glass from sticking or bursting due to excessive temperature difference when it comes into contact with the conveying wheel 2.

[0055] Furthermore, a plurality of blowing boxes 9 are installed between two adjacent flexible shafts 1;

[0056] The blowing boxes 9 extend along the Y-axis direction, and a plurality of the blowing boxes 9 located between two adjacent flexible shafts 1 are arranged at intervals along the X-direction.

[0057] like Figure 1-3 As shown, cooling air can be blown to the tempered glass after bending through the blowing box 9, so that the tempered glass can be quenched and tempered.

[0058] Furthermore, the support seat 4 further includes two shaft sleeves 44;

[0059] Two ends of the connecting seat 42 are respectively fitted with two shaft sleeves 44;

[0060] Both ends of the connecting seat 42 are rotatably embedded in the two rotating chambers 410 through the corresponding shaft sleeves 44 .

[0061] like Figure 4 and Figure 5 As shown, the shaft sleeve 44 can reduce the rigid contact and friction between the two ends of the connecting seat 42 and the rotating cavity 410, and improve the rotation flexibility and service life of the two ends of the connecting seat 42.

[0062] Furthermore, the shaft sleeve 44 is provided with a limiting ring 441;

[0063] The limiting ring 441 surrounds the circumferential edge of the shaft sleeve 44 on a side close to the rotating cavity 421 , and the limiting ring 441 is used to abut against the edge of the corresponding rotating cavity 410 .

[0064] like Figure 5 As shown, the limiting ring 441 can improve the installation stability of the shaft sleeve 44 and prevent the shaft sleeve 44 from passing through the rotating cavity 410 and getting loose during operation.

[0065] Furthermore, the connecting seat 42 includes two halves that are mirror-symmetrical in upper and lower directions, and the rotating cavity 421 is formed by closing two semicircular grooves that are symmetrically distributed in upper and lower directions.

[0066] like Figure 4 and Figure 5 As shown, the connecting seat 42 is divided into two mirror-symmetrical halves, which is more conducive to processing and forming, and can also improve the installation convenience of the spherical bearing 43.

[0067] Preferably, the shaft sleeve 44 is made of polytetrafluoroethylene.

[0068] The shaft sleeve 44 made of polytetrafluoroethylene has better wear resistance and service life.

[0069] In summary, if Figure 1-5 In the embodiment of the present invention shown, the flexible shaft mounting structure for glass bending and tempering is characterized in that the flexible shaft 1 is rotatably mounted in the rotating cavity 421 through a joint bearing 43, and the two ends of the connecting seat 42 are rotatably inserted into the two rotating cavities 410, respectively. Each flexible shaft 1 is connected to a plurality of support seats 4 through corresponding joint bearings 43, so that the flexible shaft 1 can rotate in the support seat 4, and the phenomenon of the flexible shaft 1 being stuck and failing to rotate will not occur.
